Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.
Compound leaves look like a bunch of leaves that all come from the same stem. However, this stem is really a petiole, and the individual blades connected to it are called leaflets (little leaves).An ash leaf is an example of a compound leaf: In addition to simple and compound leaves, there are some obvious differences in leaf shape.he arrangement of a plantâs leaves on the stem is called phyllotaxy. Though most leaves perform photosynthesis, some plants have modified their leaves to do other things. Cacti are a great example of this: those prickly spines are actually leaves. The green part of a cactus is actually a photosynthetic stem.
